So I have installed Ansys 18.2 on a Google Cloud instance in the hopes of completing my project simulations faster. This VM has 8 cores (Xeon CPU @2.3 GHz) and has 32 GB RAM. I have made the mesh files locally on my personal laptop so that I only need to open Fluent in the VM and not waste money.

But when I opened parallel Fluent with 8, 6 or 4 processes (3D, Double-precision) and tried to read the .msh file they all crashed with the same error as logged above. Is there any way to get past this error and continue with the simulation. A very quick reply would be appreciated as I have my exams coming up too...Thank you for y'all time.


EDIT: I have now started the meshing process from scratch on the VM via Workbench and the same error is hown in Fluent. An other error log Workbench shows is this:

Ansys.Fluent.Cortex.CortexCommandFailedException: An error occured in FLUENT while applying case and settings informatins.
An error occured in FLUENT while applying case and settings informatins.
at Ansys.Fluent.Cortex.CortexCommunicator.SendMessage (String msg, String msgKey, String errorMessage, Boolean waitForReply)
at Ansys.Fluent.FluentCommunicator.UpdateSetupInfo(Di ctionary`2 info)
at Ansys.Fluent.Data.SetupData.ReadCaseModelInfo(IFul lContext context)

Does this help anyone understand what is going on? Please help guys...

Hello

Were you able to resolve this?
I am having a similar crisis.

Thanks

not enough RAM memory
make a new mesh with less number of finite volumes

Thanks
I'll test that out
